checked-c-convert tool: struct variable containing a checked pointer not initialized

---

I noticed this issue when converting the Icecast code. In the file src/thread/avl.c and various others.

The C compiler doesn't complain when a struct variable is not initialized, but the Checked C compiler does. The checked-c-convert tool doesn't give an warnings that an initialized struct variable was seen.

I created a small example for reference:

Original C code:

typedef struct _link_node {
  struct _link_node *parent;
  int width;
} link_node;

int add_to_link_node(link_node *node) {

  node->width += 5;

  return node->width;
}

int main() {

  link_node here;
  here.width = 10;

  return add_to_link_node(&here);
}

checked-c-convert output:

typedef struct _link_node {
  _Ptr<struct _link_node> parent;
  int width;
} link_node;

int add_to_link_node(_Ptr<link_node> node) {

  node->width += 5;

  return node->width;
}

int main() {

  link_node here;
  here.width = 10;

  return add_to_link_node(&here);
}

The checked-c-convert output will produce the error:
error: struct variable 'here' containing a checked pointer must have an initializer
